To all 'whom'z't may concern:

Beit known that I, Evnn'rl Ascun, a citizen ofthe United States, and a vresident of Clara City,.in`the county of Chippewa and State of Minnesota, yhave invented anew and Improved Ratchet-Brace, of whichthe following is a full, clear, and exact description.

This invention. relates to .braces Aor brackets andi-has" for an-.obj'ect the provisionof an improved Aconstruction which .may beused as a clamping .brace or bracket and alsoas a drill brace.`

Another object in viewy is the provision of an improved arrangement of brace which may be Aadjusted in length.

A further object of theinvention is :the provisiony of a .brace with ,an` adjustable resting member adapted to face in a plurality of dierent directions-sov as to coact with-objects in different places in respect to the drill carried by the opposite end ofthe bracket. Y

'A further object of the invention is the provision of a bracket having a foot at one end. and a drilling contrivanceat thev opposite end arranged tov move the drill toward the end carrying the foot or in an opposite direction.

In the accompanying. drawing:

' Referring to the accompanying' drawing by numerals, l indicates a har telescopically fitting into a tubular sleeve 2 which sleeve is bent for producing a hollow arm 3 .at the lower end, while'the hollow bar 1 is bent forproducinfr a supporting arm 4 atfthe upper end. rm' 3 is provided with one or more projections 5 fitting into notches 6 on the'y fitti-ng 7,- which fitting has a supporting member 8 slidingly fitting into arm' 3, andi a base 9 adapted to engage an articleer engage the shoulder when the device is in vuse according tothe particular position thereof.

l/Vhen itis desiredto clamp an article or bore a hole therethrough the parts. are arranged .asshowny inFig. l, but in. caseit is desired to-.bore aholethrough an object noty capable of Vbeing positioned betwcenthe arms 3 and 4 the base 9 is turned over to the dotted:.positionssliowny inl 5F ig. 1 and the wheel v10 and `all .parts ycarried thereby4 are turned-.over so thatfthe drillV 11 will be pointed `in kthe opposite direction. `The sleeve -,2.is provided with a number ofaper tures v1-2-.-for receiving.- -the end of. loc-king'. -pin ltsaid lockingpin ittingin-to any` ofthe apertures 12 according tothe position of the bar. l-.which carries thelock-ing pin.- :This locking pin is shown in deta-i-lin'Fig. 6 and consists. of an. ordinary roundpinl pressed by a springy 14,-,whichspring and pi-n are locked in a bore-[15in bar l. i-t-.is de sired to change the positionof the bar 1 pin y'13. is: depressed until the .sleeve 2 canhbe rotated av short distance w hereupon..- the pin y13 will be yout ofregister and the bar 1 maybe moved to anydesired position and the parts turned .back-.so that thepinwill'register with. some ofthe apertures 1-2. into whirh it will snapwhenbrought into saidregister. An aperturek 16 is also provided atright angles toy aperture 12 whereby the` arm?) and kassociateparts maybe held .at right angles toarm. 4. "This is desirableunder some circumstances, as forinstancewhere the .standards or .other vbracing supportis located-out of linewith theplatesftobe drilled.-

' The fitting 10. is af'T-shaped iitting and. is threadedon to arm 4. so as to rotatearound said. armor rather swung-to two opposite extreme. positions, namely to; the .position shown in Fig. 1- andptheposition diametrically opposite.` 1 Inorder to: lockthe iitting when it isI inveither position a springN17-is` providedy having, a bend fitting, .in-to the bore 18. of body V19 for fitti-ng. into the notch20 when the fitting is -in the. position:shown in Fig. land into notch 21 when inthe opposite position. s A groove22 is provided to accom-x modate the bod-y19 when depressed so' that the fitting 7 may rotate and when moved for half revolution a. spring is released and is allowed to snap intothe opposite slot. The." fittingA is internally threaded as-shown in Fig. 2 ror accommodating thev externally threaded'slleeve23, which sleeve is provided with an voperating member 24,-. which is preferably in the shape of a ydisk so that it maybe readily moved at any point. r"'l`hesleeve 23 acts against'the" shoulders 25g. ofthe tool' Cil be fed as fast or slow as desired. A ratchet wheel 27 is rigidly secured to the upper end of the shaft 28 which carries the socket 26, the connecting means being threads, key or any other desirable means. A crank arm 29 is loosely mounted on the rod 28 and a bracing arm 30 is also loosely mounted on rod 28. The arms are raised as shown in Fig. 1 so as to straddle the ratchet wheel 27 whereby the tool 3l pivotally mounted on these arms may be continually maintained in contact with the ratchet by a spring 32 so that as the knob 33 is moved back and forth and arm 29 is moved back and forth the rod 28 and socket 26 and whatever is connected with said socket will be rotated by an intermittent motion. It is, of course,

tool receiving member having a shank or rod extending through the fitting, means for rotating said rod, and an adjusting member threaded into the fitting, said adjusting member having an annular' flange whereby same ma be moved at any point around the fitting for adjusting said tool receiving member toward and from said foot.

2. A bracket of the character described comprising a body adjustable longitudinally provided with an arm at each end, a foot arranged on one of said arms, a fitting arranged on the other arm and formed so as to rotate around the arm, a catch mounted on the last mentioned arm for locking the fitting in any of its adjusted positions, a tool receiving socket formed with a rod extending through said fitting, an adjusting member connected with the fitting and acting on said socket for moving the tool carried thereby toward and from said foot, and a power member connected with said rod for rotating the same.

3. A brace of the character described comj prising a body substantially U-shaped with adjustable so as to act in either of two direc tions, a rotatable tool receiving member arranged in the tool receiving member, and means for operating said tool receiving member.

4. In a ratchet brace, in combination a body having spaced opposite arms, said body consisting of two relatively adjustable parts, a tool carrier mounted upon one of said arms and movably carried thereon whereby it can be disposed inwardly or outwardly with respect to said arms, and a base rotatably mounted upon the other of said arms whereby it can be disposed inwardly or outwardly with respect Vto said arms.

5. In a ratchet brace, in combination a body having spaced opposite arms, said body consisting of two relatively adjustable parts, a tool carrier mounted upon one of said arms and movably carried thereon whereby it can be disposed inwardly or outwardly with respect to said arms, means for securing said tool carrier in a plurality of positions, a base rotatably mounted upon the other of said arms whereby it can be disposed inwardly or outwardly with respect to said arms, and means for securing said base in a plurality of positions.

6. In a ratchet brace, in combination a body having spaced opposite arms, said body consisting of two relatively adjustable parts, means for locking together said parts of the body in different positions of adjustment, a tool carrier rotatably mounted upon one of said arms and movably carried thereon, whereby it can be disposed inwardly or outwardly with respect to said arms, and a brace rotatably mounted upon the other of said arms whereby it can be disposed inwardly or outwardly with respect to said arms.

7. In a ratchet brace the combination of a body substantially U-shape and having two parts telescopically associated, means for locking the telescoping parts together, a base rotatably carried by one of the legs of said body, means for locking the base in a position nearest the opposite leg of said body and in one substantially diametrically opposite, a sleeve rotatably carried by the other leg of said body, a tool carrying member rotatably mounted on said sleeve, a latch arranged to lock the sleeve so that said tool member is nearest the opposite leg of said body or in an opposite position, means for 120 rotating said tool member about its aXis, and a means for forcing said tool member away from or toward the base.

8. In a ratchet brace, the combination of a body substantially U-shaped with the parts connecting the two legs of the U telescopif cally fitting one into the other, a plurality of-apertures in the outer telescoping member of said body, a spring actuated locking; pin slidably mounted in the inner telescoping member'of said body so as to engage any in the two said positions, a tool Carrying one of said apertures and so lock the two member rotatably carried on the other arm'` members together, a base, a support fixed to of said body, means for rotating said tool 10 said base rotatably carried by one of the member about its aXis, and means for forclegs of said body so that said base may be ing said tool member away from or toward turned toward or away from the opposite the base.
